CAR-WHEEL.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed may 2, 1914. Serial No. 835,941.

This invention relates to certain improve ments in railway rolling stock and has relation more particularly to a car wheel; and the object of the invention is to provide a wheel of this general character having novel and improved means whereby the intermediate or web portion of the wheel is capable of movement independently of-the rim or peripheral portion and whereby such relative independent movements are accomplished with a minimum of friction.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our 1111- proved car wheel whereby certa n important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantaeous for use,'all as will be hereinafter more fully set forth.

The novel features of-the invention will be carefully set forth in the amended claims.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanyin drawings, wherein- Fi re 1 is an elevational view, with a part i i'oken away, of a wheel constructed 1n accordance with an embodiment of our invention; Fig. 2 is a vertical sectionalview taken through Fig. 1; Fig. 3 is an enlarged fragmentary sectional view taken through the peripheral portion of the wheel as disclosed in the preceding views and illustrating in detail the means for retaining the anti-friction members in operative position; Fig. 4 is a view somewhat similar to Fig. 2 but illustrating a further embodiment of our invention; Fig. 5 is a view similar to Fig. 3 but illustrating the retaining means for the anti-friction members as disclosed in the form of our invention illustrated in Fig. 4; and Fig. 6 is a fragmentary view in section of one of the plugs employed in the form of our invention set forth in Figs. 4 and 5.

As disclosed in the accompanying drawings, 1 denotes a car wheel axle of the usual type, and operatively engaged with such axle 1 is the web 2 of a car wheel, the periphery of such web being provided, as disclosed in Figs. 1 and 3 with the annular race-way 3, in which is adapted to project the anti-friction members 4, disclosed in such figures as roller bearings, such bearlngs being also received within an annular race-way 5 produced in the inner wall of the rim member 6 which constitutes the tread surface of the wheel structure. By this arrangement, it will be readily perceived that the web portion 2 is capable of movement or rotation independently of the rim or tread member 6, which arrangement is particularly advantageous at such times when a car, to which the wheel is applied, is rounding a curve, and thus overcoming a disadvantage which is believed to be manifest to those skilled in the art to which the present invention appertains.

In order that the wheel structure may be properly assembled, we provide the rim or tread member 6 at a predetermined point with the radially disposed opening 7 through which the anti-friction members 4 may be directed in order to properly position such members between the web 2 and the rim or tread member 6.

The radial opening 7 is adapted to be closed after the anti-friction members have been properly applied by a block 8 snugly fitting within such opening and of a size to have its outer face, when applied, substan tially flush with the periphery of the member 6 and its inner face flush with the base of the race-way 5 and in order to maintain such block 8 against accidental displacement, we provide the same with a lateral opening 9 adapted to register with suitable openings 10 produced in the adjacent side portions of the rim or member (land through such registering openings is adapted to be directed a suitable anchoring member 11, herein disclosed as a conventional rivet.

As is believed to be self-evident and as is particularly illustrated'in Fig. 4, the antifriction members may comprise the spherical bodies 12, and, when so desired, such spherical bodies may be disposed in dupli- Ell cute series, in which event the web 2 is provided with the concentric unnulnr race-ways of requisite form in cross section and the or trend member 6* is provided with the corresponding or complementary rsce-Wnys 315 in this latter form of our invention end is purticulorly in Fig. the trend memher 3 is provided With the invvnrdly diverging openings 16 and 17 in communion tion with the race-Weir 15, whereby the sphericel bodies 312 may be properly applied, the upper extremities of." the openings heinp; seporsted by the septum 22. in oroer to close the divergingopenings l6 and it, one of such openings, herein disclosed us iii, hos snugly engaged therewith the blocli or plug 19 huving its outer extremity disposed on u requisite incline and suituhly convened whereby such outer elrtremity of the block 19 will be disposed in substantial continuity with the wells of the opening 17, in which opening is adopted to be inserted the block 2d. in order to maintain these blocks 19 end 20 upgoinst displacement, the rivet 21 is disposed-therethrough and through the odjecent portions'ot the trend member or rim ti whereby it will he reudily perceived that a single rivet or retninins member serves to maintain both oi the hloclrs in proper position,

From the foregoing description, it is thought to be obvious that u cur Wheel constructed in accordance with our invention is of extremely simple end compurotively ensive nature end is purticulurly Well udepted for use by reason or? the-convenience and facility with which it msy he ussembled end by renson ot the etiiectiveness with which it performs its functions, and it will else be obvious thut our invention is susceptihle of some change and modihcution without'mst/eriul departure from the principies end spirit thereof end for this reuson We do not to be understood us limiting ourselves to the precise nrronpgement and.

intense formation of the severul ports-herein shown in carrying out our invention in practice,

Having thus fully/described our invention What We desire to cluim and secure by Letters Potent, is

i. A car Wheel comprising u Web portion provided with concentric unnulur ilunges in its periphery, a treudmember surrounding such vveh portionand provided with racewnys complementary to the race-ways of the Web portion, anti-friction members adopted to be received Within the complementary rucevreys, such treudmember being, provided with inwardly diverging openings through which the anti-friction members are udupted to be directed, blocks for closing such openings, and means common to both of such blocks for maintaining the same oguinst displacement.

2. A car Wheel comprising it Web portion provided with concentric ennulur flanges in its periphery, a tread member surrounding such web portion and provided with racevvoys complementary to the race-whys of the web portion, anti-friction members adopted to he received within the complementary ruce-Woys, such trend member being provided with inwardly diverging openings through which the anti-friction members ore adopted to be directed, blocks for closinp; such openings, and rhesus common to both oi? such blocks for maintaining the some uguinst displacement, one of such hloclrs intersecting the second block.

lln testimony whereof We hereunto shin our signatures in the presence of two Witmesses.
